The point-is-in-polygon package is a lightweight package that was developed to check if the coordinates of a point are in the coordinates of a polygon.
const polygon = new Polygon([
[
{ x: 200, y: 200 },
{ x: 500, y: 100 },
{ x: 800, y: 200 },
{ x: 800, y: 400 },
{ x: 500, y: 500 },
{ x: 200, y: 400 },
{ x: 200, y: 200 },
],
]);
const point = new Point({
x: 300,
y: 400,
});
point.isInPolygon(polygon); // true
